The fuse box and BCM are separate components, resulting in excessive space consumption and increased costs. Although integrated control devices have emerged, their functions are fixed, lacking configurability, intelligent diagnostics, and display capabilities. Summary of the Invention

[0003] To better address the aforementioned issues, this invention provides a highly integrated automotive intelligent power distribution box that occupies less space and effectively reduces production costs.

[0004] To achieve the above objectives, embodiments of this utility model provide an automotive intelligent power distribution box, including an upper cover, a main body, a lower cover, a BCM control module circuit board, and a fuse box circuit board. The BCM control module circuit board and the fuse box circuit board are arranged parallel to each other within the main body. The portion of the main body corresponding to the fuse box circuit board is provided with multiple fuses, multiple relays, multiple through-hole diodes, multiple through-hole resistors, a digital tube, a potentiometer knob, a diagnostic button, and multiple indicator lights connected to the fuse box circuit board. The portion of the main body corresponding to the BCM control module circuit board is provided with two CAN communication interfaces, 12 input interfaces, 30 output interfaces, and two voltage output interfaces connected to the BCM control module circuit board, and these are integrated into multiple plug-in ports.

[0036] In the automotive intelligent power distribution box of this utility model embodiment, the fuse box circuit board 3 is located on the upper side of the BCM control module circuit board 4. The two circuit boards are parallel to each other by multiple plastic support columns arranged between them, and are then integrated into the main body 2 by welding the columns together.

[0037] The lower side of the main body 2 is connected to the lower cover 5 by bolts, such as the multiple self-tapping screws 51 with washers shown in the figure for connecting the lower cover to the main body on the periphery; the lower cover 5 can be used to position, fix and protect the BCM control module circuit board 4. The upper side of the main body 2 is connected to the upper cover 1 by a retaining spring 11, which facilitates the adjustment of the electrical components on the fuse box circuit board 3 after opening the upper cover 1. Preferably, the upper cover 1 is made of transparent plastic material and does not cover the multiple plug-in ports 8.

[0038] In practical applications, a sealing ring 22, such as a waterproof rubber gasket, is provided at the connection between the main body 2 and the upper cover 1 and lower cover 5 to achieve the dustproof and waterproof function of the power distribution box. Additionally, a waterproof vent 12 is provided on the upper cover 1, and a waterproof vent valve or waterproof vent membrane 13 is provided in the vent to achieve the ventilation and heat dissipation function of the power distribution box without compromising the dustproof and waterproof performance of the product.

[0039] The automotive intelligent power distribution box of this embodiment has customizable functional logic. Different functions and configurations can be achieved by flashing different programs, facilitating batch management and increasing the device's platform integration. The output channel control mode can be freely set, enabling local parameter condition control or communication control. The current protection threshold and protection time of the output channel can be arbitrarily configured. The digital input of the input channel can be freely configured to be active high or low, and the analog input can be configured as voltage or switching quantity.

[0040] In practical application scenarios, other devices or components can also be installed in the automotive intelligent power distribution box of this utility model embodiment to realize the actual application or other functions of the automotive intelligent power distribution box. For example, a fuse clip 35 is also provided on the main body 2 for operating the fuse; as another example, a gateway module, Bluetooth module, etc. are also provided on the part of the main body corresponding to the BCM control module circuit board and the fuse box circuit board.

[0041] This intelligent power distribution box can perform power distribution, signal acquisition, gateway functions, blue chip functionality, UDS flashing, parameter calibration, fault diagnosis (e.g., supporting the ISO14229 diagnostic protocol), and network management (e.g., meeting the SAE J1939 protocol; supporting OSEK direct network management). Each function in the intelligent power distribution box is represented by an input status bus signal and an actual load status bus signal, and the logical state of each function must be consistent with the actual load bus signal. Configuration and information reading are performed via local CAN bus communication, and a dedicated host computer program can also be used for standalone configuration and information reading. When a fault occurs, the intelligent power distribution box automatically performs fault diagnosis and sends the fault code to a digital display for display. If multiple fault codes are present, the digital display will cycle through them at 2-second intervals, making fault handling simpler and clearer.

[0042] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
